[0019] The following is combined with Figure 1 - Figure 4 This application is described in further detail.

[0020] Reference Figure 1 - Figure 4A prefabricated aluminum profile connector comprises a connecting seat 1 and a plurality of aluminum profiles 2 connected to the connecting seat 1, a connecting groove 3 is provided on the aluminum profile 2, a positioning block 4 is fixedly provided on the connecting surface of the connecting seat 1 and the aluminum profile 2, an expansion block 5 is fixedly connected to the positioning block 4, a plurality of expansion blocks 5 are distributed on the positioning block 4, a tapered groove 6 is provided at a position close to the plurality of expansion blocks 5, and a tapered pin 7 matched with the tapered groove 6 is also included, a connecting column 8 is fixedly provided on the tapered pin 7, a plurality of connecting columns 8 are provided on one side of the connecting seat 1, and a combination seat 9 is also fixed at one end of the plurality of connecting columns 8 on the same side, the tapered pin 7, the connecting column 8, and the combination seat 9 are distributed in a plurality of groups on the connecting surface of the connecting seat 1 and the aluminum profile 2, and a driving component for squeezing the tapered pin 7, the connecting column 8, and the combination seat 9 outward is also provided inside the connecting seat 1.

[0021] Reference Figure 3 A limiting cavity 15 for sliding limiting of the combination seat 9 is opened inside the connecting seat 1, the connecting column 8 passes through the outer wall of the connecting seat 1 and the positioning block 4, the tapered pin 7 is located in the tapered groove 6, and the combination seat 9 is located on the side of the limiting cavity 15 close to the center position of the connecting seat 1 when the extrusion block 12 does not squeeze the compression rod 10. At this time, the tapered groove 6 and the tapered pin 7 are also in a non-pressurized state. After the extrusion cavity 11 squeezes the compression rod 10, the combination seat 9 moves to the other end of the limiting cavity 15. At this time, the tapered pin 7 squeezes the tapered groove 6 to expand the expansion block 5.

[0022] Reference Figure 3 - Figure 4 After the tapered pin 7 moves outward in the tapered groove 6, the expansion block 5 expands and is squeezed into the connecting groove 3. The tapered structure of the tapered groove 6 and the tapered pin 7 expands and presses the expansion block 5 into the connecting groove 3 after extrusion fitting, thereby realizing the internal connection between the connecting seat 1 and the aluminum profile 2. The positioning block 4 plays a positioning effect before connection and increases the connection reliability after connection.

[0023] Reference Figure 3 - Figure 4 The driving component includes a compression rod 10 fixed on the side of the combination seat 9 away from the connecting column 8, an extrusion cavity 11 opened inside the connecting seat 1, and an extrusion block 12 sliding in the extrusion cavity 11. The movement of an extrusion block 12 can simultaneously drive multiple compression rods 10 to move, thereby realizing the connection of aluminum profiles 2 on multiple surfaces of the connecting seat 1, which has the advantage of convenient operation.

[0024] Reference Figure 3 The pressure rod 10 also runs through the extrusion cavity 11, and a matching chamfer is provided between the contact surface of the extrusion block 12 and the pressure rod 10. The chamfer plays a guiding role when the two are in contact, facilitating the extrusion fit between the two.

[0025] Reference Figure 3The driving member also includes a bolt 13 rotating on the extrusion block 12, and a threaded hole 14 threadedly matched with the bolt 13 is opened in the connecting seat 1. The extrusion block 12 moves in the extrusion cavity 11 and cooperates with the pressure rod 10 through the spiral of the bolt 13 and the threaded hole 14.

[0026] Working principle: during connection, the bolt 13 is in the withdrawn state, the extrusion block 12 does not contact the compression rod 10, the aluminum profile 2 is inserted into the connection seat 1 in turn, the connection groove 3 is inserted into the expansion block 5 and the positioning block 4, at this time, the aluminum profile 2 is stabilized and does not move, the bolt 13 is rotated by a tool, and the bolt 13 drives the extrusion block 12 to move inside the extrusion cavity 11 through the spiral with the threaded hole 14. Since the front end of the extrusion block 12 and the compression rod 10 are provided with matching chamfers, the extrusion block 12 contacts with the compression rod 10 during the movement, and drives the compression rod 10 to move under the action of the chamfer, and the compression rod 10 drives the combination seat 9 to move in the limiting cavity 15, the tapered pin 7 and the connecting column 8 move synchronously, the tapered pin 7 squeezes the tapered groove 6, squeezes the expansion block 5 outward, and the outside of the expansion block 5 is pressed tightly in the connection groove 3. During the advancement of the extrusion block 12, the compression rod 10 is squeezed into place in turn, thereby fixing the aluminum profile 2 connected to the connection seat 1;

[0027] When it is necessary to disengage the installation, rotate the bolt 13 in the opposite direction, and the extrusion block 12 will be released from the extrusion on the compression rod 10. At this time, the tapered pin 7 moves toward the connecting seat 1 under the action of the tapered groove 6, and then the expansion block 5 is released from the extrusion between the connecting groove 3, and the aluminum profile 2 can be disconnected from the connecting seat 1.

[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
